I have a slight dilema with regard to a modular layout I am currrently putting together. The problem is the storage space I have in which to store 7 modules that are each 4' x 30". The structures that I am using on each module take up a large amount of space height-wise as I have to store each module above the others in a small closet. Is there any reason why I cannot have removable structures that I will have to set-up and take down each time the layout is moved? Having removable structures seems like a logical solution to my problem but I am not sure if I am missing something that may cause more problems.
